Thanks for your support. 


Kindly note our Pixel 4 and Pixel 4 XL battery cases have been released on our website and Amazon.



Pixel 4 Battery Case 6500mAh


Pixel 4 XL Battery Case 8000mah



It would be the only option we have for both two cellphones at the moment. We will update via here and social media if there is a slim battery case will be made for them.


Thanks for reading.
